36 Claims.

This invention relates to combined typewriting and accounting machines having a laterally shiftable traveling carriage, and is particularly directed to a power mechanism for driving said 5 traveling carriage in its working direction for letter-spacing and tabulating, and for returning said traveling carriage from tabulated position to starting position.

The majority of accounting machines used in 10 the business world at the present time are equipped with a laterally shiftable traveling carriage similar to that used on typewriters, and certain of these machines also have, in addition to the usual accounting machine keyboard and 15 mechanism, a typewriter keyboard and mechanism for typing various data, of a descriptive nature, upon the record material, which is supported by a platen roll mounted in the traveling carriage. I

The traveling carriages of such machines are frequently large and heavy, as they must not only be long so as to be capable of handling wide ledger sheets, having a plurality of vertical col- 2 umns for the recording of various data pertaining to particular business systems, but said carriages also carry control means for controlling the functioning of the accounting machine in accordance with the" columnar position of said traveling carriage. A typical example of record material used in such machines is the statement sheet used by banks in the balancing of individual checking accounts.

The traveling carriages for accounting ma- 3 chines are generally movable from a starting position in a working or tabulating direction, and when such movement is completed the carriage is returnable to starting position. The usual practice is to use a spring motor consisting of a o spring-actuated drum and its associated drawband for moving the traveling carriage in its working direction. When the tabulating or working movement of the traveling carriage is completed, mechanical means driven by the oper- 5 ating motor becomes automatically effective to return the traveling carriage to starting position.

The weight of the traveling carriage frequently makes it necessary to apply excessive tension 50 to the spring motor in order to have said carriage move at the desired speed. This results in excessive rebounding of the carriage when it is stopped after being tabulated through several intervening columnarpositions to a particular 55 column. When the traveling carriage is moved only a short distance for letter-spacing, under control of the typewriter keys and the escapement mechanism, or when tabulated from one column on the ledger sheet to the next, the spring motor drive works very satisfactorily. However, in some bookkeeping systems it is necessary to tabulate the carriage from the first column on the ledger sheet to the last column thereon or to some other intervening column, and this is when the deficiencies of the spring motor become more manifest.

One of the inherent characteristics of the spring-driven traveling carriage is that it gets under way slowly, when released for tabulation,

and accelerates rapidly; therefore, when a long tabulation of the traveling carriage is terminated abruptly by the stop mechanism, the momentum of said carriage causes excessive rebound. Inasmuch as the columnar position of the traveling carriage controls certain functions of the accounting machine, if the machine is released for operation during the interval that the traveling carriage is rebounding it is quite possible that the Wrong control will be exercised by said carriage over the accounting mechanism due to the incorrect position of the traveling carriage at that moment.

In the present machine the spring motor for for moving the traveling carriage in its working direction has been replaced by a fluid-operated power device, or connection, and this power device is driven by a separate motor and is therefore in no way dependent upon the accounting machine operating mechanism, this latter being a desirable feature when the accounting machine operating motor is of the start-stop type.

In addition to moving the carriage in its working direction the fluid-operated power device is also arranged to return the traveling carriage m to starting or initial position.

Therefore, it is broadly an object of this invention to provide a fluid-operated power device, or connection, for moving the traveling carriage of an accounting machine or typewriter in its a working direction and for returning said traveling carriage to starting position.

Another object of this invention is the provision of a fluid-operated power device, nonpositive in action, for moving the traveling carriage of an accounting machine or tyepwriter from starting position in letter-spacing or working direction, and an automatic reversing mechanism for returning the carriage to starting poaltion.

Still another object of this invention is to supply a continuously running hydraulic power device, non-positive in action, and operating independently of the accounting machine operating mechanism, for moving the traveling carriage of an accounting machine or typewriter from initial or starting position in a tabulating or letter-spacing direction, said device being provided with a transmission mechanism for reversing the action thereof to return the traveling carriage from tabulated position to starting position.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompanying and form a part of this specification.

GENERAL DESCRIPTION The present invention is shown embodied in the well known accounting machine, fully illustrated and described in Letters Patent of the United States, No. 1,203,863, issued November 7, 1916, to Halcolm Ellis, Patent No. 1,819,084 issued August 18, 1931, to Emil John Ens, and Patent No. 2,082,098 issued to Raymond A. Christian, June 1, 1937. Only the mechanism of the machine, pertinent to the present invention, will be described in detail in this specificaton, as reference may be had to the above patents for a full disclosure of the complete machine.

The accounting machine is provided with a laterally shiftable traveling carriage supporting a platen roll, adapted to present record material wound therearound to the printing mechanism. The carriage is adapted to be tabulated from column to column, to present different columnar divisions of the record material to the printing mechanism. If desired, the machine may be equipped with a typewriter keyboard and typewriter mechanism for typing various data upon the record material, and when so equipped, the machine is provided with an escapement mechanism, operated by the typewriter keys, for letterspacing the traveling carriage. The escapement mechanism also holds the carriage against tabulating movement.

Releasing the carriage for tabulating movement renders the escapement mechanism ineffective and moves a stop plunger into the path of a series of stops, adjustably mounted on the carriage to correspond to the different columns of the record material. Tabulation of the carriage is terminated by one of the stops contacting the stop plunger, which is unlatched by the impact and immediately moves out of the path of said stop. The stop then contacts an escapement control plunger, which is likewise unlatched by the impact and immediately causes the escapement mechanism to again become efiective to hold the carriage against further tabulation.

The traveling carriage is driven in either tabulating or return direction by a continuously running motor, which drives a control shaft, which is in turn geared to one member of a hydraulic connecting device, the other member of which is geared to a carriage drive shaft. The carriage drive shaft has slidably mounted thereon and rotatable therewith, two similar clutch members adapted to alternately engage corresponding clutch members, integral with bevel reversing gears free on said drive shaft. The bevel gears in turn mesh with a similar bevel gear mounted on a short shaft, which also carries a spur gear which meshes with the teeth of a horizontal rack secured to the traveling carriage. The two slidable clutch members mounted on the carriage drive shaft are connected for unitary shifting movement by a shifting bar, controlled by the carriage control shaft, which results in one of the clutch members being engaged with its corresponding bevel gear, and the other clutch member being disengaged, at all times.

When the traveling carriage is in its extreme righthand, or starting, position the clutch mem her that drives said carriage in its letter-spacing or working direction is engaged. Consequently the hydraulic connecting device constantly but non-positively urges the traveling carriage in its letter-spacing or working direction, but said carriage is normally restrained against such movement by the escapement mechanism. Operating one of the typewriter keys or depressing one of the tabulating keys releases the escapement mechanism, thereby permitting the hydraulic device to move the traveling carriage in letterspacing direction until the escapement mechanism again becomes effective to terminate such movement of the carriage. When the traveling carriage nears the end of its letter-spacing movement, a cam block, mounted thereon, renders the mechanism effective that shifts the clutches for the bevel gears, whereupon the letter-spacing clutch is disengaged and the return clutch is simultaneously engaged to reverse the direction of movement of the carriage. This causes the hydraulic device to return the traveling carriage towardstarting position; near the termination of which movement the cam block on the lefthand end of the traveling carriage again causes the clutches for the bevel gears to be shifted, whereupon the return clutch is disengaged, and the letter-spacing clutch is simultaneously engaged.

It is evident that the fluid connection between the members of the hydraulic device forms a yielding or cushioned drive against which the travelingcarriage may be held stationary. When the traveling carriage is held against tabulating movement, maximum pressure is built up in the hydraulic device; therefore when the traveling carriage is released for tabulating movement, this excess pressure causes said carriage to immediately get under way at full speed, and when the excess pressure is dissipated, the traveling carriage travels along at a uniform rate, the hydraulic connection acting as a governor. The tabulating movement of the traveling carriage is abruptly terminated by the stop mechanism, whereupon the hydraulic connection immediately builds up pressure and maintains a steady pull upon the traveling carriage, which practically eliminates rebounding thereof, irrespective of whether said carriage is tabulated a long or a short distance. v

As previously stated, the traveling carriage, when in columnar poistion, exercises certain control over the operation of the machine, such as selecting totalizers for addition and subtraction, and it is very essential that said carriage be accurately located in columnar position when the machine is released for operation so that the proper controls will be effective. The elimination of excessive rebounding of the traveling carriage, by means of the hydraulic drive, causes said carriage to be accurately located in columnar position so that the proper control will be effective upon operation of the machine, thereby permitting experienced operators who have become exceedingly fast in the handling of particular business systems to operate the machine as fast as desired.

Mechanism pertinent to the present invention will now be described in detail.

DETAILED DESCRIPTION Framework mechanism of the machine is enclosed in a suitable case or cabinet 35 (Figs. 1 and 8) which is secured to the machine base 32.

Operating mechanism States, Serial Number 697,449, filed November 10,

1933, by Charles H. Arnold, which application issued into Patent No. 2,142,341 on January 3, 1939.

The armature shaft of the motor 36 is geared to the driving member of a clutch 31, the driven member of which is connected by a link 38 to an arm 39, secured on the righthand end of a; main shaft 40, journaled in the frames 30 and 3|.

Releasing the machine for operation causes the clutch 31 to be engaged, and simultaneously closes the switch for the motor 36. Rotation of the motor 36, by means of the link 38 and the arm 39, oscillates the main shaft 40 first counter-clockwise and then back to normal position through an approximate angle of 60 degrees. One such oscillation of the main shaft 40 is referred to herein as a cycle of operation, and after said shaft has completed its cycle of operation the clutch 31 is automatically disengaged and the switch for the motor 36 is simultaneously opened to terminate operation of the machine. The arm 39 '(Figs. 5 and 8) carries a roller 4|, which cooperates with a camming slot 42 in a plate 43, secured on a leading frame shaft 44. Consequently one cycle of movement of said arm 39 rocks the shaft 44 first counter-clockwise and then back to normal position. I I

The arm 39 (Fig. 5) is connected by a shiftable link 45 to an arm 46 flexibly connected to an arm 41 secured on a printer shaft 48 journaled in the rightframe 30 and the printer framework (not shown). One cycle of movement of the arm'39, by means of the link 45, rocks the shaft 48, first clockwise and back to normal position, to cause the printer mechanism to function.

In overdraft operations the arm 39 and the shaft 40 operate automatically through four cycles of movement to transpose the complementary amount of an overdraft to a true negative amount and record said truevnegative amount. During the first three or transposing cycles of an overdraft operation the link 45 is automatically disconnected from the arm 39 to render the printing mechanism inoperative so that the results of the transposing cycles will not be recorded upon the record material. In the last cycle of an overdraft operation the link 45 is automatically connected to the arm 39 so that the true negative amount of the overdraft will be recorded during this cycle. The overdraft printer controlling mechanism, mentioned above, is not hereshown but is fully disclosed in U. S. Patent No. 2,079,355 issued May 4, 1937, to Charles L. Lee.

Keyboard and actuator mechanism The keyboard of the accounting machine consists of a plurality of rows of amount keys, and

one row of control keys, the latter adapted to control all functions of the machine with the exception of addition. Inasmuch as the keyboard mechanism is substantially duplicated in each amount bank, it is believed that the description of the penny bank, shown in Fig. 1, will be sufficient for a thorough understanding of the keyboard mechanism.

The keyboard framework consists of a top plate 48, two end plates (not shown) and a partition plate 58 for each row of amount keys, said keyboard framework forming an integral unit which is suspended between the frames 30 and 3| and secured in place by means of screws in cooperation with holes in opposite edges of the keyboard top plate 48 and corresponding threaded holes in the frames 30 and 3|. Each amount bank consists of nine amount keys 5|, numbered from to 8 inclusive, slidably mounted in the keyboard framework by means of the undercut upper ends of the stems of said keys, which extend through corresponding slots in the top plate 48, and by means of square studs 52 on the lower ends of the stems of said keys, which extend through vertical slots (not shown) in the corresponding partition plate 50. Springs (not shown), which are laced around studs in the keys 5| and stationary studs in the partition plates 50, urge said keys upwardly to maintain the shoulders on the upper ends thereof in contact with the bottom of the plate 48.

Each amount bank has a locking detent 53 and a control plate 54 mounted for horizontal sliding movement between rollers 55, journaled on studs 56 secured in the partition plate 50 and each amount key 5| carries a stud 51 which cooperates with a corresponding hook on the detent 53 and a corresponding angular camming surface on the control plate 54. A spring 58 tensioned between the control plate 54 and the detent 53 urges them rearwardly and forwardly, respectively.

Depressing one of the amount keys 5|, by means of the stud 51 in cooperation with the angular nose on the corresponding hook of the detent 53, shifts said detent rearwardly, against the action of the spring 58, until the hook passes beyond said stud 51, whereupon the spring 58 returns the detent 53forwardly, to latch the key in depressed position. During operation of the machine the detent 53 is locked against rearward movement, by mechanism not shown, to lock the depressed key against release and to lock theother amount keys in this bank, against depression.

Depressing one of the amount keys 5| also causes the stud 57, in cooperation with the corresponding angular camming surface on the control plate 54, to shift said control plate forwardly, against the action of the spring 58, to cause the forward end of said control plate, in cooperation with a bent-over ear 58 on a zero latch 68 mounted on a rod 6| supported by the keyboard framework, to rock said zero latch counterclockwise. Counter-clockwise movement of the latch 60 disengages a hook thereof from a block 62 secured to an actuator 63, for this particular amount bank, mounted for horizontal sliding movement by means of a slotted rod 64 and a slotted bar 65, both of which are supported between the frames 30 and 3|.

Depressing one of the amount keys 5| also moves the stud 52 therein in the path of the corresponding one of a series of graduated steps 65 on the actuator 63. The actuator 53 has a vertical slot 6'! which straddles a stud 68 in a downward extension of a printer control segment 68, free on the shaft 44. A spring 70, tensioned between the segment 68 and the cross-bar of a leading frame 1|, said cross-bar extending between similar arms '|2 secured to the shaft 44, maintains a beak '13 of said segment in contact with said cross-bar.

Initial movement counter-clockwise of the shaft 44, as explained in connection with Fig. 8, carries the leading frame 1| in unison therewith and said leading frame, bymeans of the spring 10 (Fig. l), carries the segment 68 and the actuator 83 in unison therewith until the corresponding one of the graduated steps 56 contacts the stud 52 of the depressed amount key 5|. This positions the actuator 83 and the segment 88 in proportion to the depressed key and said segment, by means of a link 14 connecting an extension of said segment to a printing sector 15 for this particular amount bank, also positions said sector in accordance with the depressed amount key. The leading frame completes its initial movement counter-clockwise, independent of the segment 88, flexing the spring 10. The sector 15 is pivotally connected to the upper end of an arm 16, free on the shaft 48, and a control plate Tl, free on the shaft 48, is also connected to said arm 16.

When the segment 88 moves out of zero position, a stud 18 in an extension thereof, in cooperation with an arcuate surface on the tail of a zero elimination pawl 18, rocks said pawl counterclockwise, against the action of a spring 80, to move a tooth of said pawl out of engagement with a corresponding tooth of the plate 11, to free the arm 18 and sector 15 for printing movement. After the actuator 63 and the segment 68 have been positioned, an aliner 86 is rocked into engagement with one of a series of teeth 81 to retain said segment 88, the actuator 63 and the sector 15 in set positions until printing has been effected.

After the printing sector 15 has been positioned and after the leading frame II has completed its initial movement counter-clockwise, an impression latch 84 is rocked counter-clockwise out of engagement with a tooth 88 on the plate 11 to release said plate, the arm 18, and the sector 15 to the action of a spring 88. The spring 88 moves the plate TI, the arm 15 and the sector 15 rearwardly causing said printing sector, in cooperation with an inking ribbon (not shown), to print the value of the depressed key upon the record material wound around a platen roll 88 mounted in the framework of a traveling carriage presently to be described. After printing has been effected, the aliner 86 is rocked out of engagement with the teeth 81, and the leading frame 1| is returned to its original position, and in its return movement clockwise, returns the segment 68 and the actuator 83 to zero positions.

Immediately after the actuator 83 has been returned to zero position, and prior to the termination of machine operation, a key release shaft 8| (Fig. 1), journaled in the keyboard framework, and an arm 82, integral therewith, receive counter-clockwise movement. Counterclockwise movement of the arm 82 causes a stud 83 therein, in cooperation with an angular camming surface on an upward extension 84 of the detent 53, to shift said detent rearwardly to release the depressed key. The stud 83, in cooperation with an angular camming surface on an upward projection 85 of the control plate 54, shifts said control plate forwardly, to rock the zero latch 58 to ineffective position. However, this shifting of the control plate 54 is of importance only in total and sub-total operations and is merely an incidental occurrence in adding and subtracting operations. After the amount keys have been released, the zero latch 50 again becomes effective to retain the actuator 63 and printer control segment 69 in zero positions, as here shown.

Totalizers In its present embodiment the machine of this invention has two totalizer lines, a #I or balance totalizer line (Fig. l) and a #2 or adding totalizer line. However, it is merely a matter of assembly to add additional totalizers in back of the #I and #2 totalizers. The totalizer lines have a wheel for each denominational order and these wheels are adapted to be actuated by rack teeth in the rearwardly disposed ends of the actuators 63.

In adding operations the wheels of the selected totalizer are engaged with the actuators 63 after said actuators have completed their initial movement rearwardly, and return movement forwardly of said actuators adds the amount set up on the keyboard in the wheels of the selected totalizer. After the actuators have completed their return movement forwardly, the wheels of the selected totalizer are disengaged therefrom. In subtract operations, the wheels of the #I or balance totalizer are engaged with the actuators 63 prior to their initial movement rearwardly, which movement reversely rotates said wheels to subtract therefrom the amount set up on the keyboard. Amounts are carried or transferred from lower to higher order totalizer wheels by means of the well known transfer mechanism, shown in part in Fig. 1.

In total and sub-total operations the wheels of the selected totalizer are engaged with the actuators 63 prior to the initial movement rearwardly of said actuators. The shaft SI and the arms 92 function to release any amount keys inadvertently depressed and to rock the zero latches 60 to ineffective positions, so that the actuators 63 will be free to move under control of the leading frame II. The actuators 63 in their initial movement rearwardly reversely rotate the wheels of the selected totalizer until a tooth on the trans fer cam (not shown), carried by each totalizer wheel, contacts the add-transfer pawl to locate the wheels of the selected totalizerin zero position and to position the actuators 63 and the printing sectors 15 in proportion to the amount on said totalizer wheels. In total operations, after the amount of the total has been recorded, the wheels of the totalizer are moved out of engagement with the actuators 63, prior to their return movement forwardly, and therefore remain in a cleared or zeroi'zed condition. Insubtotal operations the wheels of the selected totalizer remain in engagement with the actuators 63 during their return movement forwardly, andare thus returned to their original positions.

As previously stated, the machine embodying this invention has a typewriter keyboard and mechanism for typing data of a descriptive nature upon the record material. The typewriter mechanism will be explained later in connection with the traveling carriage mechanism.

Traveling carriage The platen roll 90 (Fig. l) is mounted in the- Hydraulic connection mechanism As previously explained, the traveling carriage 96 is driven in its working or letter-spacing direction and in its return direction through a hydraulic connecting device which will now be explained.

Secured on the back of the traveling carriage 96 (Figs. 1, 8 and 10) is a horizontal rack I02, the

inverted teeth of which mesh with a gear I03 secured on one end of a short shaft I04 journaled in a bushing supported by upturned ears I05 of a shelf-like plate I06 secured to the back of the case 35 and supported by angular legs I0! extending between said shelf and the case 35.

Fast on the other end of the shaft I04 is a bevel gear I08 which meshes with similar bevel reversing gears I03 and H5 free on a shaft IIO journaled in upturned ears III of the bracket I06. Integral with the gear I09 is a clutch member I I2 having teeth adapted to cooperate with similar teeth in a clutch member I I3 slidably mounted on the shaft IIO by means of' clutch cuts, in said member, in cooperation with corresponding tenons on a sleeve I I4 secured on said shaft IIO. Thus the clutch member I I3 is arranged to revolve in unison with the shaft H0 and to be shifted horizontally in relation to said-shaft, at the same time. The bevel gear II5 has integral therewith a clutch member I I6, the teeth of which 'are adapted to cooperate with the teeth of a clutch member I I1, similar to the clutch member H3, and connected to a sleeve IIO, integral with the shaft H0, in exactly the same manner as the clutch member H3 is connected to the sleeve H4.

The hydraulic device, which moves the traveling carriage in its working and return directions,

is driven by a small continuously operating motor I worm gear I24 (Fig. 10), fast on the lower end of a vertical shaft I25, joumaled in the housing I23, in a bent-over portion of the bracket I20, and in a bushing in the shelf I06. Fast on the shaft I25 isa gear I26, which meshes with and drives a gear I21 secured on a trunnion I20 (Fig.-

4), the lower end of said trunnion bein journaled in a bushing in the bent-over portion of the bracket I20 and the upper end integral with a bottom plate I29 of a hydraulic connection housing I30. i

The hydraulic connection housing consists of a series of plates including the plate I29, an oil recess plate I35, a recess cover plate I36, an intermediate, cover plate or baflie I3'I and a top-plate I38, all of said plates secured in an integral unit by means of-a series of screws I39. Free on an upward tenon of the trunnion I28 (Figs. 4 and 9) is a gear I40 which meshes with companion gears HI and I42 free on studs I43 and I44 secured in the plate I29. The gear I40 is secured to the lower end of a shaft I 45 which extends through an oil seal I46, contained in a bushing in the cover plate I38, and the upper end of said shaft I45 is journaled in a bushing in the shelf I 06. Secured to the upper end of the shaft I45 (Figs. 8 and 10) is a bevel gear I41 which meshes with a similar bevel gear I48 secured on the righthand end of the shaft IIO.

The periphery of the teeth of the gears I40, HI and I42, (Fig. 9) closely fit corresponding arcuate surfaces in the recess in the plate I35, and together.with a viscous fluid, such as oil, contained in said recess form a hydraulic connection which, when the housing I (Fig. 8) is revolved by the motor II9, tends to revolve the shaft I in the same direction. The revolving action of the hydraulic connection is regulated by screws I49 and I50 (Figs. 4 and 9) threaded into by-pass slots cut in similar web portions of the recess in the plate I35. In other words, the screws I49 and I50 form a means of re ulating the flow of oil between the two-intake and two output oil compartments, formed by the gears I40, HI and I42 and the recess in the plate I 35, and this regulation of the flow of oil controls the revolving influence that the housing I30 has upon the shaft I45.

The opening between the plates I36 and I31 forms a supply reservoir which is partly filled with oil and is connected to the intake compartments of the hydraulic connection by holes I5I in the plate I36, through which the oil is supplied to the hydraulic connection as needed. The plate I31 forms a baffle to prevent the oil from working out of the top of the housing I 30 and a flanged bushing I52, secured on the shaft I45, whirls the oil, that tends to creep up the shaft I45, back into the supply reservoir.

The hydraulic connection forms a non-positive connection between the motor I I9 and the traveling carriage 96 for driving said traveling carriage in its working or tabulating direction, and in its return direction. However, it is obvious that the traveling carriage may be held stationary against the action of the hydraulic connection or, if necessary, returned in the opposite direction against the action of said clutch. When the traveling carriage is retained stationary, the action of the hydraulic connection simply builds up pressure, which is dissipated in the form of heat.

Control of carriage movement Normally the clutch members H6 and H1 (Fig. 10) are engaged, and this tends to drive the traveling carriage in its working or tabulating direction. When the traveling. carriage approaches the end of its tabulating movement, clutch control mechanism is rendered effective to automatically disengage the clutch member I I1 from the member H6 and simultaneously engage the member II3 with the member II2, whereupon the action of the hydraulic connection is reversed to return the traveling carriage to its extreme righthand or initial position. When the carriage nears the end of its return movement the clutch control mechanism is again rendered effective to disengage the clutch members I I2 and H3 and simultaneously engage the clutch members H6 and H1, so that the action of the hydraulic connection again tends to drive the traveling carriage in its working direction. The mechanism for controlling engaging and disengaging of the clutch members II 3 and H1 will now be described.

The clutch members H3 and H1 (Figs. 10, 15 and 16) each has an annular groove into which extend, respectively, studs I53 and I54 secured to bars I55 and I56 respectively, each being slidably mounted on a bar I51, by means of two studs in each of said bars I55 and I56 in cooperation with their respective horizontal slots in said bar I51. The bar I51 is also mounted for horizontal sliding movement by means of horizontal slots therein in cooperation with studs I56 and I59 in similar brackets I 60 and I6I secured to the shelf I06. A spring I62 tensioned between the bars I55 and I56 urges said bars toward each other and forms a yielding connection to prevent damage in case the teeth of the clutch members H3 and I I1 engage the tops of the teeth of their correspondingclutch members, when said members H3 and II 1 are shifted to effective position. In the center of the bar I51 (Figs. 8, 10 and 16) is a stud I63 engaged by a helical cam groove cut in the periphery of a shifting cam I64 free on a shaft I 65 journaled in upturned ears I66, I61 and I68 of the shelf I06. The shaft I65 is operatively connected to the motor II9 by a bevel gear I80,

fast on said shaft, which meshes with a similar gear I8I secured on the upper end of the shaft I25.

Referring to Figs. 8, 10 and 14, integral with the cam I64 is a drum cam I69 having a node I10, on the face thereof, adapted to cooperate with studs HI and I12 in the arms of a yoke I13 free on a vertical rod I14 supported by the shelf I06 and a bracket I 15 secured to said shelf. Extensions of the studs HI and I12 (Fig. 14) en gage an annular groove in a clutch member I16, slidable on the shaft I65, and having tenons I11 which engage corresponding spline cuts in a collar I18 secured on said shaft I65. The teeth of the clutch member I16 are adapted to cooperate with teeth I19 cut in the cam I69. A spring I (Figs. 11 and 14), connected to the yoke I13 and a latch I86 pivoted to the bracket I06, is tensioned to urge the teeth of the clutch member I16 into engagement with the teeth I19. However, the latch I86, in cooperation with a tooth I81 on the lower arm of the yoke I13, ormally holds the clutch member I16 in ineffective position, as here shown.

The latch I86 (Figs. 11 and 14) has a camming slot I88 therein, which cooperates with a stud I89 in one end of a bar I90 connected by a link I9I to the lower arm of the yoke I13. A spring I92, tensioned between the lower arm of the yoke I13 and the bar I90, urges said bar counter-clockwise to yieldingly hold the stud I89 in the righthand or upper portion of the slot I86. The stud I89 (Figs. 10 and 11) coacts with the end of a lever I93 pivoted on a stud I94, in the shelf I06, said stud also forming a pivot for the latch I86. The other end of the lever I93 is pivotally connected to a bar I95, slotted to embrace a stud I96 secured in the shelf I06.

As previously explained, with the clutch members H6 and H1 engaged, as shown in Fig. 10, the hydraulic mechanism drives the traveling carriage toward the left or in a working or tabulating direction. When the traveling carriage nears the end of its tabulating movement, a cam block I98 (Fig. 10) mounted thereon, engages the angular nose of the bar I and shifts said bar rearwardly to rock the lever I93 counterclockwise, causing said lever, in cooperation with the stud I89, to rock the latch I86 out of engagement with the tooth I81 on the arm of the yoke I13. This releases the yoke I13 to the action of the spring I85 (Figs. 11 and 14) which immediately rocks said yoke clockwise to engage the teeth of the clutch member I16 with the teeth I19.

The motor II9 continuously revolves the shaft I65 in the direction indicated by the arrows. Consequently the clutch member I16 immediately revolves the cams I69 and I64 in unison with said shaft I65. After the cams I69 and I64 have completed 180 degrees of movement or one-half a revolution, the node I18 ofthe cam I69 engages the stud I12 to restore the yoke I13 counter-clockwise and to disengage the clutch member I16 from the teeth I19. A retaining member, later described, arrests and retains the cams I69 and I64 in the normal position or in said 180-degree moved position. The latch I86, which has been rendered effective in a manner presently to be described, again reengages the tooth I81 to retain the yoke I13 and the clutch member I16 in ineffective positions.

Clockwise engaging movement of the yoke I13 (Fig. 11), after the latch I86 has been disengaged therefrom,'causes a bent-over ear I99, on an extension of the lower arm of said yoke I13, to engage and rock the bar I 98 clockwise, against the action of the spring I92. Clockwise movement of the bar I98 moves the stud I89 out of the upper portion of the slot I88, whereupon the camming action between said stud I89 and said slot I88 assists the spring I85 in returning the latch I86 clockwise into the path of the tooth I81, so that said latch will be effective to engage said tooth to retain the yoke I13 in its normal or ineffective position when the yoke is returned to this position by the cam I18, and regardless of whether or not the block I98 retains the lever I93 and stud I89 in-latch disengaging positions.

180 degrees rotation of the cam I64 (Figs. 10 and 16) causes the groove therein, in cooperation with the stud I63, to shift the bar I51 toward the left, as here viewed, to disengage the clutch member II1 from its corresponding member H6 and to simultaneously engage the clutch wardly to again disengage the latch I86 fromthe tooth I81 to engage the clutch member I16 (Fig. 14) with the teeth I19, whereupon the shaft I65 revolves the cams I69 and I64 another 180 degrees of movement, until the node I18 of the cam I64 engages the stud I1I to disengage the clutch member I16 from the teeth I19 in exactly the same manner as explained above. This one-half revolution of the cam I64 shifts the bar I51 toward the right, as viewed in Fig.

18, to reengage the member II 1 and to simul-' taneously disengage the clutch member II3 to.

again permit the hydraulic clutch device to yieldingly urge the traveling carriage in its working or letter-spacing direction.

When the carriage is returned to starting position the escapement mechanism, later to be described, holds said carriage against tabulating movement, consequently the block I99 retains the lever I93 in latch disengaging position, therefore in order to prevent repeat engaging movements of the yoke I13 and unnecessary shifting of the clutch members I I3 and I I1, it is necessary to render the latch I86 effective in the manner explained above, irrespective of the position of said lever I93.

A spring pulled retaining pawl 238 (Figs. 18, 13 and 14) pivotally mounted on a bracket 23I secured on the shelf I86, in cooperation with two diametrically opposed V notches in a disc 232 integral with the cams I64 and I69, retains said cams, the bar I51 and the clutch members H3 and I I 1 in either of their two positions, when the clutch member I16 is disengaged.

The cam blocks I98 and I99 (Figs. 1 and 12) are adjustably mounted, in relation to the angular nose of the bar I95, by means of screws I82 threaded in said blocks, in cooperation with a series of holes I83 in a downward extension of an angle bar 288 secured to the back of the traveling carriage 96, said downward extension of the bar 288 fitting snugly in horizontal slots in said cam blocks I98 and I99.

Carriage escapement mechanism As previously explained, the hydraulic clutch device normally functions to constantly urge the traveling carriage in working or letter-spacing direction, and said carriage is restrained or held against such movement by an escapement mechanism which is operated by the typewriter keys to letter-space the traveling carriage, and which is rendered ineffective by the tabulating mechanism when the traveling carriage is released for tabulating movement. The manner in which the typewriter keys operate the escapement mechanism will now be described.

Directing attention to Figs. 3 and 5, a typewriter key lever 28I, which isrepresentative of the full complement of typewriter keys, is pivoted on a rod 282, supported by the frames 38 and 3|, and said key lever carries a stud 283, s

which cooperates with the camming slot inv a type operating lever 284, pivoted on a rod 285, supported by the frames 38 and 3I. The upper end of the lever 284 cooperates with a universal bar 286 mounted in slots in two similar forwardly extending arms of a yoke 281, said arms bein pivoted on studs 288 in similar bent-over portions of a bracket 289, said bracket in turn being pivoted on studs 2 I8 in extensions of the escapement frame 33.- Rearward extensions of the yoke 281 (Figs. 2 and 3) support a pin 2I I, which fits loosely in a hole in a downward extension of a lever 2I2 free on a stud 2I3 secured in the frame 33.

Pivotally connected to an upward extension of the lever 2I2 is a bracket 2 I4, having secured in a bent-over ear thereof one end of a rod 2I5 the other end of said rod fitting loosely in a holein an extension of a lever 2 I6 free on a stud 2 I1 fast in the frame 33. Also fulcrumed on the stud 2I1 is an escapement pawl 2I8 urged counter-clockwise by a spring 2 I 9 to normally maintain a tooth thereofv in engagement with the teeth of an escapement ratchet 228 secured on the downward end of a vertical shaft 22I journaled in a bushing 222 (Fig. 2) in the frame 33. The shaft 22I has secured on the upper end thereof a pinion 223 which meshes with a horizontal rack 224 secured to the framework of the traveling carriage 96. The spring 2I9 normally maintains an extension of the pawl 2I8 in contact with an eccentric 225, by means of which the tooth of said pawl is adjusted in relation to the teeth of the ratchet 228.

The lever 2! 6 is adjusted in relation to the yoke 261 by means of an adjustable collar 226, free on the rod 2|5, and its cooperating adjusting and locking nuts. A spring 221, tensionecl between the pivot for the bracket 2 I4 and an extension of the lever 2l6, normally maintains said extension in contact with the collar 226.

Depressing the key 2! (Fig. 5) rocks the lever 204 counter-clockwise, causing the upper end of said lever, in cooperation with the universal bar 266, to shift the yoke 201 forwardly. Forward movement of the yoke 201 rocks the lever 2!2 (Fig. 2) clockwise, which movement by means of the rod 2i5 rocks the lever 2l6 also clockwise to disengage the tooth of the escapement pawl 2i8 from the teeth of the ratchet 220. This frees the traveling carriage 96 to the action of the hydraulic device, which letter-spaces said traveling carriage toward the left, as viewed in Fig, 10, until a tooth of said ratchet 220 contacts a stop pawl 228 pivoted on the lever 2l6. When the key is released the yoke 201 is spring-returned rearwardly to return the lever 2!2 (Fig. 2) counter-clockwise, which in turn permits the spring 221 to return the lever 2!6 counter-clockwise (Fig. 3) to move the stop pawl 228 out of the path of the teeth of the ratchet 22D and to simultaneously move the escapement pawl 2I8 back into the path of said teeth, to permit the traveling carriage to move the equivalent of one tooth of said ratchet 220 to letter-space the record material wound around the platen roll of said carriage.

When the traveling carriage is returned, from the terminus of its letter-spacing movement, to starting position the ratchet 220 is reversely rotated, whereupon the teeth thereof ratchet over or by-pass the tooth of the escapement pawl 2 !8.

In addition to the reversing cam block I99 (Fig. 10) a positivestop is provided to insure termination of return movement of the traveling carriage. This mechanism includes a lug 229 on a return marginal stop 235 (Fig. 6) adjustably mounted on a stop bar 236 secured to the framework of the traveling carriage 96, in cooperation with the upper end of a stop plunger 231 slidably mounted in a recessed portion of the frame 34 and retained in said recess by means of screws 238, in cooperation with slots in said plunger 231.

Typewriter tabulating mechanism The upper end of the plunger 231 is always in the path of the lug 229 to insure termination of the return movement of the traveling carriage 96 in the manner explained above, and in addition manipulative means is provided for raising said plunger into the path of typewriter tabulating stops mounted on the stop bar 236 and for simultaneously disengaging the escapement mechanism to permit the traveling carriage to tabulate under influence of the hydraulic mechanism until such movement is terminated by one of said stops contacting said plunger 231.

A spring 235 (Fig. 6) urges the plunger 231 upwardly, to normally maintain a square stud 240 therein in contact with a rounded nose on an extension of a lever 24! pivoted on a stud 242 in the frame 34. A spring 243, which is strong enough to overcome the action of the spring 239, urges the lever 24! clockwise to normally maintain an extension 244 thereof in contact with a pad 234 formed on the frame 34. The lever 24! positions the plunger 231 so that the upper end thereof is just beneath and out of the path of a lug 245 on a typewriter tabulating stop 246, adjustably frame 30.

mounted on the stop bar 236. The lever 24! has a nose 241 which underlies a hook-shaped extension of a lever 248 pivoted on a stud 249 in the frame 34. A notch 25!), in another extension of the lever 248, engages a rearward extension of a lever 25! pivoted on a stud 252 (Fig. 5) in the The lever 25! terminates in a fingerpiece 253, which is conveniently located to the right of the typewriter keyboard where it may be easily reached by the operator.

Depressing the lever 25! rocks the levers 248 and 24! counter-clockwise and clockwise, respectively, as viewed in. Fig. 5, and clockwise and counter-clockwise, as viewed in Fig. 6, against the action of the spring 243, to lift the rounded nose of said lever 24! away from the stud 240 to permit the spring 239 to carry the plunger 231 upwardly into the path of the lug 245 on the stop 246. The extension 244 of the lever 24! (Figs. 5 and 6) overlies a stud 254 in a plunger 256 mounted to slide vertically in a slot in the pad 234 on the frame 34. The plunger 256 (Fig. 2) has an aperture into which projects an extension of a bell crank 251 pivotedon a bracket 258 secured to the frame 34. The bell crank 251 is pivotally connected, by a link 259, to one arm of a lever 260 free on a stud 26! in the frame 33. Another arm of the lever 26!! is connected, by a link 262, to an arm of a yoke 263 rotatable on a rod 264 supported by downwardly extending ears of the frame 33.

Depression of the lever 25! (Figs. 5 and 6) and consequent downward movement of the extension 244 of the lever 24!, causes said extension, in cooperation with the stud 254 to shift the plunger 256 downwardly to rock the bell crank 251 counter-clockwise, as viewed in Fig. 2, which in turn rocks the lever 26!] and the yoke 263 clockwise. Clockwise movement of the yoke 263 causes an upwardly extending arm 265 thereof to engage an extension 266 (Fig. 3) of the escapement pawl 2!!! and rock the tooth of said escapement pawl out of engagement with the teeth of the ratchet 220, to release the traveling carriage 96 to the action of the hydraulic device, shown in Fig. 10, which immediately tabulates said carriage until the lug 245 (Fig. 6) on the stop 246 contacts the plunger 231. Releasing the manipulative lever 25! permits the spring 243 to return the lever 24! clockwise to move the upper end of the plunger 231 out of the path of the lug 245 and to permit a spring 261 (Fig. 2) to return the lever 26!) and the yoke 263 counter-clockwise, to eifectuate the escapement mechanism to hold the carriage against further tabulating movement.

Automatic tabulating mechanism In addition to the manual means-for tabulating the traveling carriage, just described, there is also an automatic means sometimes called the accounting machine tabulating means, for tabulating the traveling carriage to align the different columns on the record material with the accounting machine and typewriter printing means. Ordinarily, the automatic tabulating means functions, during machine operation, immediately after printing has been effected. However, the automatic tabulating means is subject to manual control, by means of which it may be made to function at will without operating the machine. The automatic tabulating mech anism is not in any way connected with or dependent upon the manually operated typewriter tabulating means just described, and may be properly termed a complete tabulating mechanism in itself, having its own set of stops and their associated control and stop plungers.

Referring to Fig. 5, initial movement counterclockwise of the arm 39 moves the link 45 upwardly, as previously explained, causing an angular nose on a spring-pulled hook 268, mounted thereon, to by-pass a stud 269 in a lever 219, loose on a stud 211 in the frame 39, whereupon said hook 268 latches over said stud 269. Return movement clockwise of the arm 39, and consequent downward movement of the link 45 causes the hook 268, in cooperation with the stud 269,

to carry the lever 219 downwardly in unison therewith.

The lever 219 (Figs. 5, 6 and 7) is slotted to receive one end of a lever 212 fulcrumed on a stud 213 in the frame 34, while another extension of said lever 212 underlies an arm of a lever 214 pivoted on a stud 215 in the frame 34. A spring 216 urges the lever 214 counter-clockwise as viewed in Figs. 6 and '7, to normally maintain a raised surface thereof against the pad 234.

Downward movement of the lever 219 rocks the lever 214 clockwise, against the action of the spring 216, causing a pad on the bottom surface of said lever, in cooperation with the stud 254, to shift the plunger 256 downwardly (see also Figs. 2 and 3) to disengage the escapement pawl M8, in the manner explained earlier herein, to

release the traveling carriage 96 to the action of the hydraulic device, which immediately moves said carriage toward the left (Fig. 10) or in tabulating direction. 7 a

The lever 214 (Fig. 7) carries a stud 211 which extends through a slot in the lower end of a tabulating stop plunger 218, the upper end of which fits loosely in a slot 219 in a built-up portion of the frame 34. A torsion spring 289, in cooperation with a stud 28! in the bar 218, urges said ,bar upwardly in unison with the lever 214.

Clockwise movement of the lever 214 causes a square stud 282 therein to move beyond the latching surface of a hook- 283, free on a-stud 284 in the frame 34, whereupon a torsion spring 285 urges said hook clockwise into the path of the stud 282, to obstruct counter-clockwise movement of the lever 214 when the hook 268 (Fig. 5) rides off the stud 269, near the end of return movement downwardly of the link 45. Clockwise movement of the hook 283, under influence of the spring 285, causes a hump 286 thereon to engage and rock the plunger 218 counter-clockwise, into contact with the left wall (Fig. '1) of the slot The stud 28! (Fig. 6) extends through a slot in an escapement control plunger 292 adjacent the stop plunger 218, the upper end of said plunger '29: fitting loosely in the slot 219, and the lower end being pivotally connected to a lever 293 fulcrumed on the stud 215. The lever 293 is similar in outline to the lever 214 and has a downwardly extending pad which cooperates with the stud 254 in exactly. the same manner as said lever 214. A spring 294 urges the plunger 292 counter-clockwise to normally maintain an undercut portion on the upper end thereof in contact with a square stud 295 in an arm 296 pivoted on a screw stud 291 in the frame 34. The arm 296 is urged clockwise by a spring 298' into contact with a stop stud in the frame 34. Thestud 281 carries the plunger 292 upwardly in unison with the plunger 218 until the notch, in said plunger 292, moves beyond the stud 295, whereupon the spring 294 urges said plunger 292 counter-clockwise to engage said notch with the stud 295, to obstruct downward movement of said plunger 292.

Upward movement of the plungers 218 and 292, in the manner explained above, moves their respective extensions 299 and 399 into the path of a stopping lug 39I (Fig. 5) on a tabulating stop 392 adjustably mounted on the stop bar 236. Near the end of the tabulating movement, toward the right as viewed in Figs. 6 and '1, of the traveling carriage, the lug 39! engages the extension 299 and carries the plunger 218 clockwise into contact with the righthand wall of the slot 219 in the frame 34, whereupon tabulating movement of the traveling carriage is terminated. This clockwisemovement ofthe plunger 218 rocks the hook 283 out of engagement with the stud 292 to release the lever 214-to the action of the spring 216, which immediately returns said leverand the plunger 219 downwardly to the position'shown in 'Fig. '7. The, projection 299 protrudes far enough beyond the projection 399 'of the plunger 292 to'prevent the lug 39! from engagingsaid' projection 399 when the plunger 213 is rocked into contact with the right wall of the slot 219.

Downward movement of the plunger 218, as

explained above, moves the projection 299 thereof out of the path of the lug 39I, thereby permitting the traveling carriage to tabulate a slight distance farther, until said lug 39l contacts the projection 399 of the plunger292 and rocks said plunger clockwise to disengage the notch therein from the stud 295. Upon being thus released, the

plunger 292 and the lever 293 are returned downwardly, and counter-clockwise respectively, to normal position, by a torsion spring 29! (Fig. 6) thereby releasing the plunger 256 and connected mechanism, to the action of the spring 261 (Fig.

2), which immediately rocks the yoke 263 counv tar-clockwise to move the arm 265 (Fig. 3) out of engagement with the extension 266, of the pawl- 2l8, to permit said pawl to return into engagement with the teeth of the ratchet 229 to hold the traveling carriage against further tabulating movement. I r

In case the traveling carriage 96 is returned toward starting position when the plungers 218 and 292 (Figs. 6 and 7) are in upward or effective positions, angular surfaces on the upper ends of said plungers permit the lug 39l to cam said plungers downwardly until said lug by-passes said plungers. The slot in the lower end of the plunger 218 permits such downward movement I thereof independently of the lever 214, and the spring-pulled arm 296 permits such downward movement of the plunger 292. After the lug 39! has by-passed the plungers 218 and 292, they are immediately spring-returned upwardly to effective positions.

Sometimes itis desirable to tabulate the traveling carriage without operating the machine, and in the machine embodying the present invention this is effected by depressing a tabulating key 393 (Fig. 5), which renders the accounting machine tabulating mechanism effective by rocking the lever 219 clockwise inexactly the same manner as the hook 268 rocks said lever upon operation of the machine.

The upper end of the key 393 passes through a slot in the keyboard top plate, while the lower end of said key is slotted to embrace a stud (not shown) in a bracket (not shown) secured to the mally maintain a bent-over ear of said latch in contact with the edge of the key 303. The spring 305 also normally maintains the key 303 in its upward or undepressed position.

Depressing the tabulating key 303 causes the latch 304, in cooperation with an extension 301 tabulating mechanism to function in exactly the same manner as explained above. The finger 31 I permits the lever 210 to move independently of the arm 309 and connected mechanism, when said lever 210 is operated automatically by the hook 263. After the tabulating mechanism has been rendered effective, continued depression of the key 303 causes an extension 3 of the latch 304 to engage a stud 315 in the frame 30 to disengage said latch from the extension 301 to prevent obstruction of the downward movement of the plungers 218 and 292 (Fig. 6) in case the tabulating key 303 is retained depressed.

Operation It is believed that a thorough understanding of the operation of the hydraulic drive for the traveling carriage will have been obtained from a perusal of the foregoing specifications. Nevertheless, a brief outline of operation will now be given.

The stop bar 236 (Figs. 1 and 6), generally carries one of the stops 302 for each columnar division of the record material, and these stops are properly located on said bar 238to position their corresponding columns on the record material opposite the accounting machine recording mechanism. In addition to stopping tabulating movement of the traveling carriage the stops 302 also have one or more downwardly depending camming lugs 312 which, in cooperation with the upturned ends of correspondinghanging bar levers 3i3, select and condition the diiferent totalizers of the machine for addition, and select and condition the #1 or balance totalize'r for addition or subtraction.

With the traveling carriage 96 in its starting position, which is determined by the first stop 302 in cooperation with the plungers 210 and 292 (Fig. 6), the data to be printed in the first column of the record material is set up on the keyboard, and upon operation of the machine this data is printed in the first column. After printing has been completed, the hook 268 (Fig. 5) rocks the lever 210 clockwise to release the traveling carriage to the action of the hydraulic device, which immediately moves said traveling carriage in a tabulating direction until the stop 302 for the second column of the record material contacts the plungers 218 and 292 to terminate tabulating movement of said traveling carriage. If there is any descriptive data to be typedin the second column of the record material, the typewriter,

keys are used for this purpose, after which the amount of the transaction is set up on the accounting machine keys and the machine released for operation. During operation of the machine the traveling carriage is again released for tabulation, and this sequence of operation continues as long as there are stops 302 for columnar divisions of the record material.

It has been explained that the camming lugs 312 (Fig. 6) on the stops 302, in cooperation with the hanging bar levers 3|3, select and condition the various totalizers for addition and subtraction. If the traveling carriage rebounds excessively when the tabulating movement thereof is terminated, the lugs 3l2 are momentarily moved out of register with the proper hanging bar levers and possibly into register with improper ones, and if the machine is released at this instant, the result will be mal-operation. The hydraulic device, explained above, provides a steady flow of power, not positive in its action, for moving the traveling carriage in tabulating and return directions, thereby overcoming any tendency for excessive rebounding thereof, thus eliminating the possibility of mal-operations from this source.

After printing has been completed, in the extreme righthand column of the record material, automatic tabulation of the traveling carriage causes the block I98 (Fig. 10) in cooperation with the angular nose of the bar I95 to shift the clutch members H3 and H1 to reverse the gearing for the hydraulic mechanism to cause the traveling carriage to be returned toward starting position. While the carriage is being returned in starting direction, the lugs 30! of the stops 302 ride over the angular surfaces of the plungers 218 and 292 as the functioning of the automatic tabulating mechanism, just prior to reversing of the carriage movement, left these bars in their upward positions and the escapement mechanism ineffective.

When the traveling carriage arrives at starting position the cam block I 99 (Fig. 10), in cooperation with the angular nose of the bar I15, again reverses the gearing for the hydraulic mechanism to terminate return movement of the traveling carriage. Inasmuch as the escapement mechanism is still disconnected and the tabulating plungers are still in the path of the stops 302 (Fig. 6) the traveling carriage starts moving in a tabulating direction, as soon as the block I99 (Fig. 10) reverses the gearing for the hydraulic mechanism. The traveling carriage moves in tabulating direction until the stop 302 for the first columnar position of the record material contacts the tabulating plungers 218 and 292 to locate the first division of said record material opposite the printing mechanism.
